Düsseldorf trio Nightslug (the possibly-related P. Slug, F. Slug and J. Slug) work in the self-labelled "FILTH" genre. In practice, this means super-heavy punked-out Sludge/Doom with all the subtlety of a runaway steamroller. Distinguished by very prominent bass lines and Hardcore-style vocals contributing to a truly grimy sound, the band certainly lives up to its chosen description.
